The movie credits has the couple of errors. Jerry Beyer is the one who plays the male counterpart of the Pot Couple, not Tim Murphy. David Light is the one who plays Reese, leader of the group of thugs. Not Steve Rogers, but Steve do appears in the movie in a different uncredited role as one of the thugs.
In the gas station explosion scene, the actual gas station was one owned by director Cirio H. Santiago. He had been having troubles with the current tenants not paying their lease so he blew it up on film without their knowledge. It's just one of many times this has happened in the Philippines.
